YOKE CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 787,642, dated April 18, 1905. Application filed December 9, 1904. Serial No. 236,227.

.To atZZ whom, it may concern."

Be it known that I, NOBLE H. Ron, acitizen of the United States, residing at Marceline, in the county of Linn and State ofMissouri, have invented certain new and useful Improvements in Yoke Constructions, of which the following is a specification.

This invention embodies improvements in the construction of draft devices for vehicles or the like, and comprises, essentially, peculiar formation of the neck yokes for buggies or wagons, the principle of construction being susceptible of adaptation in the construction of swingletrees and similar means;

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiments thereof are shown in the accompanying drawings, in which a Figure 1 is a perspective view of a neckyoke embodying the invention and especially designed for use for carriages. Fig. 2 is a side elevation of a yoke similar to that shown in Fig. 1, but particularly designed for use for wagons or' heavy draft-vehicles. Fig. 3 is a top plan view of a swingletree comprising a construction in accordance with the principle of construction of the yoke shown in Figs. 1 and 52. Fig. 4: is a bottom plan view of the construction shown in Fig. 1. Fig. 5 is a transverse sectional view on the line X X of Fig. 4.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The draft device comprising the invention consists, primarily, of a bar 1, having a plurality of longitudinal wings or webs 2, extending the entire length thereof. The bar 1 together with the parts 2 are of integral for mation and may be cast or otherwise formed in the actual manufacture thereof. The wings or webs 2 form a general reinforcement for the bar 1, enabling the use of a light yoke or draft member for the purposes of the invention. The wings or webs 2 taper slightly toward the ends of the member 1, and in the preferred construction four of thesewings are used, thus forming a yoke or tree of approximately cruciform.

As a yoke, the web upon the under side of the bar 1 is transversely enlarged or widened for some distance adjacent the center thereof, as shown at 3, this widened portion being provided with a longitudinal slot 4:, in which the yoke center 5 is received and secured. Transverse fastenings 6 pass through the lower wing 2, extending across the slot 4, and these fastenings pass through the member 5 in attaching the same to the bar 1. The member 5 is adapted to receive the pole of the vehicle in the usual manner, and when the yoke is used for light carriages said member 5 is made of leather or similar material. When the yoke is used for heavierdraft-vehicles. a ring is substituted for the leather support, the last mentioned construction being shown in Fig. 2 'of the drawings. The ring shown in Fig. 2 is of course held in place by fastenings 6 aforesaid. The yoke shown in Fig. 1 is designed for light vehicles and has the side webs 2 and the under web provided with open slots 7 adjacent the ends, through which the breaststraps are passed when the device is being used. In the structure shown in Fig. 2 openings 8 are provided in the ends of the lower and side webs 2, which openings receive rings 9, with which the breast-chains may be connected, if desired.

As a swingletree, the construction in Fig. 3, the bar 1 is of substantially the same construction as shown in Fig. 2, with the exception that books 10 are substituted for the rings 9. The members 10 are mounted upon the end portions of'one of the side webs 2 in a manner similar to the mounting of the members 9.'

Having thus described the invention, what is claimed as new is 1. A draft device of the class described comprising a bar having longitudinal wings at 0pposite sides and upon the under side thereof, each of said wings having adjacent open slots at the ends thereof to receive breast-straps.

2. A draftidevice of the class described,corn prising a bar having longitudinal wings or webs extending the entire length thereof, one of said wings being provided with a slot at a point between the ends thereof.

3. A draft device comprising a bar of cruciform having a plurality of longitudinalwings orwebs, the wings upon opposite sides and upon the under side of the bar being provided near the ends thereof with adjacent open slots to receive breast-straps, the uppermost wing being solid throughout its length substantially as specified 4. Adraftdevice ofthetypedescribed,comprising a bar having longitudinal wings or webs, one of said webs being transversely NOBLE H. ROE. [L 8.]
